I have a special place in my heart for post-apocalyptic types of Shows/Movies.

Love Terminator, Quiet Earth, Damnation Alley, By the Dawn's Early Light, Mad Max, The Day After, The Day After Tomorrow, etc.

Jericho on CBS really had me going. The storylines, the characters, everything about it had me glued to the TV once a week through the first two seasons....and now we don't know if it will be comming back for another season.
